Brakes

Brake defects affecting safety may qualify for California’s two-repair threshold under Cal. Civ. Code § 1793.22, which applies to defects likely to cause death or serious bodily injury. The 2020 Toyota Highlander has generated 42 NHTSA complaints related to braking, including ABS failures, grinding, reduced stopping power, and warning lights. Owner reports include: “My 2020 Toyota Highlander Hybrid has a braking issue identified in Toyota Service Bulletin T-SB-0059-23, Hybrid Regenerative Brake Transition Feeling Improvement. When going downhill and applying the brake, the vehicle lurches forward temporarily as the braking system transitions from regenerative to hydraulic braking. The first time my vehicle did this, it was very alarming and I had to take additional measures to slow my vehicle as I was driving downhill. My vehicle frequently demonstrates this problem, however, I did not report it to my local Toyota dealer because I read in an online chat group that it was a characteristic of this vehicle. Although the TSB recommends a Reprogram of the Brake Actuator Assembly Control Module, the repair is only covered under the Toyota Basic Warranty which is in effect for 36 months or 36k miles, whichever occurs first. My vehicle is past the warranty limit, and because I did not report it to my dealer previously, this repair is not covered under the TSB or the Toyota Basic Warranty. Toyota Highlander Hybrid model years 2020-2022 are affected. The Technical Service Bulletin was issued August 29, 2023, so if a 2020 model Highlander Hybrid has this problem, 2020 models would have already passed the warranty limit by the time the TSB was issued and thus would not be covered. This is a safety risk as drivers can lose control of the vehicle when braking, particularly when going downhill. The Warranty should be extended, or this problem should be elevated to a RECALL so that older affected vehicles, or those with higher mileage can be covered under warranty. Drivers should not have to pay for a recognized problem that affects the safety of this vehicle and has been identified in a Technical Service Bulletin. This problem puts drivers at risk of losing control of the vehicle and the problem can be mediated with a software reprogram. T-SB-0059.23 should be elevated to a RECALL, or extended regardless of age or mileage.” (NHTSA Complaint #11708018)

California Lemon Law — Song-Beverly Act

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.

Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2020 Toyota Highlander:

• 4+ repair attempts for the same non-safety defect without resolution
• 2+ repair attempts for a defect likely to cause death or serious bodily injury
• 30+ calendar days out of service for warranty repairs (cumulative, not consecutive)

Once the presumption is triggered, the burden shifts to Toyota to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Toyota must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.

What You Can Recover

If your 2020 Toyota Highlander qualifies as a lemon under California law, Toyota may be legally required to:

• Repurchase your vehicle — Full refund of your down payment, all monthly payments, registration fees, and incidental costs (towing, rentals), minus a mileage offset for miles driven before the first repair attempt
• Replace your vehicle — Provide a new, comparable vehicle at no cost to you
• Pay your attorney’s fees — Under § 1794(d), Toyota pays all legal fees if you prevail
• Civil penalty up to 2x damages — If Toyota willfully violated the Act, courts may award double the actual damages

Steps to Protect Your 2020 Toyota Highlander Claim

Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.

Step 2: Keep returning for repairs. You must give Toyota a reasonable opportunity to fix the defect. Visit different authorized Toyota dealers if needed and ask for written documentation of each visit.

Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), Toyota pays your fees if you win.

Step 4: Send a demand letter. Your attorney will send Toyota a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.

2020 Toyota Highlander Lemon Law Questions

How many repair attempts qualify my 2020 Toyota Highlander as a lemon?

Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.

Does Toyota pay my attorney fees?

Yes. Under Cal. Civ. Code § 1794(d), Toyota is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.

Can I file a lemon law claim without an active recall?

Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.

What is the time limit to file a lemon law claim for my 2020 Toyota Highlander?

California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
